FEEDING RECOMMENDATION:Scatter on the ground for foraging or place in a feeder. This product is a treat and is not a substitute for a regular, balanced diet.

IMPORTANCE OF CALCIUM: Research has shown that natural feed with balanced Ca:P ratios increases animal health and contributes to stronger bones and shiny feathers. Calcium is especially important for laying birds because a lack of it can result in poor laying, soft shells, and can cause behavior problems such as egg eating as the bird tries to recoup the much needed calcium.

Have trained the Guinea fowl and chickens to come running when I yell "BUGS"!!!!!
They get the Calci-yum BSF Larvae every evening :) -Dorothy A. M.

These are not like the original Calci-Yum worms Exotic Nutrition offered a year ago. The original ones were dark, flat, and hard. I bought these thinking they'd be the same, even though the packaging was different. Big mistake. They are not at all like the original Calci-Yum worms Exotic Nutrition offered. The new ones are puffy, crumble easily, and half the bag is nothing but dust. The chickens do not like them, and I've gone back to Exotic Nutrition dried mealworms. -Ginny C.

So glad I got this package. A good deal for my pocketbook and a good treat for my girls (chickens)! Like another reviewer, when I want to gather the girls, I shake the container and they come running! It's really cute and makes my husband shake his head. -LeeAnn P.

my chickens are not crazy about it - they prefer the regular dried mealworms -Nina B.

Nine out of eleven chickens love this product. I call them and they come running. I feed them these as a late afternoon snack. So they’ll eat they feed all day, in theory. -Kevin M.

In comparison to the dried mealworms this product is really not acceptable to our backyard birds. While they eat them, they don't consume them as fast as the normal dried mealworms which have been out of stock for two months. We have consumed nearly 60 lbs of the dried mealworms and only 11 of dried calci-yum worms to date. -Christopher B.

Birds seem to love it. Unfortunately so do the squirrels. Too funny. Started putting it down this Spring because the Robins were early and the ground was still frozen. I felt sorry for them so bought 11 pound bag for them. Its a good product and have since ordered another bag .The Robins do love it and have learned to eat from the feeders when they cant find worms on the ground. Sparrows also love it. -Elaine M.

My chickens go crazy for Calci-Yum Worms and their egg shells are much harder than they were this winter. They won’t touch the oyster shell supplements to their diet. -Marian

I tried these for our wild bird friends last year and they've been a bit hit throughout the winter. I like the Canadian sourcing. Expect I'll continue to get the combo pack as the dried mealworms fit the hoppers in the bluebird feeders better - the Calci-Yum Worms are a little too chubby! -Liz

We are feeding a wide variety of wild birds and they love the dried mealworms we generally buy from Exotic Nutrition.
The mealworms were out of stock so we tried the Calci-Yum Worms. We can't convince our birds to eat them at all. I am hoping the raccoons will show up and be willing to eat these.

Our chickens love these! Great product and price! I will be a return customer.

My Guinea hens didn't go after the Calci-Worms like they do the regular Dried Mealworms. So next time I will buy the regular. But love the huge bag and the price.

Great way to increase the chickens calcium intake in a treat! They love these as much as the dried meal worms. Terrific price into the bargain.
